A frontal boundary that lied across central Minnesota, was the focus for showers and thunderstorms that developed near Alexandria, and moved to the east-southeast during the afternoon, and evening hours. Other thunderstorms developed across southern Minnesota during the afternoon, and early evening and produced mainly large hail. Tornadoes occurred during the mid afternoon hours, and mainly confined to areas south and east of Glenwood, Minnesota. These tornadoes were brief and caused only minor damage to local trees.
